Amid the trip, the president also issued a tweet criticizing the state of California over its sanctuary city policies and its refusal to cooperate with federal immigration enforcement.

California’s sanctuary policies are illegal and unconstitutional and put the safety and security of our entire nation at risk. Thousands of dangerous & violent criminal aliens are released as a result of sanctuary policies, set free to prey on innocent Americans. THIS MUST STOP!

If we don’t have a wall system, we’re not going to have a country. Congress must fund the BORDER WALL & prohibit grants to sanctuary jurisdictions that threaten the security of our country & the people of our country. We must enforce our laws & protect our people! #BuildTheWallpic.twitter.com/NGqNueukvj
